Each of our products pages list the compatibility of Live versions, in. most cases Live 10 or higher is required.
Where the product is a MaxforLive device it is essential that you have MaxforLive installed. MaxforLive is an integral part of Ableton Live Suite and can be added as an upgrade to Ableton Live Standard by purchasing it directly through your account at ableton.com
Where a product is compatible with Live 11 this is also stated, do not take the absence of implicitly stated Live 11 compatibility to assume it is!
It is your responsibility to check for compatibility prior to purchase, no returns are possible once a product has been downloaded.
